Daniel Ricciardo celebrates his win in parc ferme as Sebastian Vettel walks past during the Azerbaijan Formula One Grand Prix at Baku City Circuit on Sunday.

Four-time world champion Vettel was given a 10-second stop-go penalty for driving his Ferrari into the back of Hamilton'sMercedes while they were following the safety auto after 19 laps on the Baku street circuit. After eight races, Vettel leads Hamilton by 14 points.

Making the most of a series of extraordinary incidents and interventions in an action-packed race, which included three safety vehicle interventions and a red-flagged stoppage, Ricciardo, who started 10th, roared home 3.904 seconds ahead of the rest to deliver his first win of the season.

Hamilton accused Vettel of "disrespectful" driving after the four-time champion pulled alongside Hamilton and appeared to deliberately swerve into him when they were behind the safety vehicle approaching the midway point of a stop-start race.

Toto Wolff has confirmed that data provided to the race stewards in Baku prove that Lewis Hamilton did not brake test Sebastian Vettel following the second safety vehicle re-start.

Ricciardo came home first ahead of Finn Valtteri Bottas of Mercedes and 18-year-old Canadian Lance Stroll of Williams.

Mercedes driver Hamilton, who won in Canada last time out and started on pole, was seemingly on course to pick up a comfortable victory and make further inroads into Vettel's championship advantage after maintaining his lead following a red flag.

"The championship battle is still respectful I don't have a problem with him, I think today's action was wrong".

"You know, it's a bit of a shame it's again me and Kimi but we've been fighting for similar positions and it's just unlucky that it's us again", said Bottas.

Despite Ricciardo s win, the race will be remembered for the angry confrontation between former world champions Vettel and Hamilton.

Hamilton claimed he was simply controlling the pace as they exited Turn 16.

"I'm willing to sort it out with him, I don't think there's much to sort out".

Vettel reacted incredulously when he learned of the 10-second penalty on lap 32, while Hamilton, whose hopes of victory were later ended when he had to pit due to a loose head rest, complained over his radio that the sanction was insufficient.

After the initial collision, the German gesticulated angrily with both hands as he then pulled alongside his rival and hit the side of Hamilton's auto.

Vettel has suggested he will call Hamilton this week to clear the air once the emotions of the Baku incident - in which Vettel steered his Ferrari into Hamilton's Mercedes after feeling he had been brake-tested ahead of a restart - have died down.

"I don't need to say anything else".

"I showed him I wasn't happy".

It took a while for us all to realise what had happened though, because in the meantime both Force India drivers collided.
